I was checking out some of the EL34 tube characteristics from the different manufacturers and ran across that term. In the Phillips Manufacturing tube characteristics they mention that a "common screen grid resistor, non decoupled, of 750 ohm" should be used for G2 for class AB. Does that mean one resistor for both tubes in the PP pair or a single resistor for each tube. I mostly see separate resistors for each tube but the terminology suggests one resistor common to both tubes. Thank you for your input, Dak
